In an earlier blog post we went over some of the Internet’s best sites for the latest on publishing, finding a critique buddy or group, and even writing prompts. But that’s of course not all the Web has to offer. Here are a few others you might want to check out:

Mashable: Think you know social media? Think again. This self-proclaimed “largest independent news source dedicated to covering digital culture, social media and technology” features helpful articles on what’s trending (hint: keep checking to see if there’s a PR opportunity for your book); the latest must-have apps; and the marketing campaigns that have caught their expert’s eyes. If you’re looking to find out who’s showing off their stuff right, visit Mashable and learn from the best.

Seth Godin’s Blog: Seth Godin is a marketer extraordinaire. No, really. Just ask American Way magazine, which called him “America’s Best Marketer.” How did he earn such a title? Well, in addition to publishing 14 books (now available in 30 languages), he’s also founded dozens of companies. Although he admits that some failed, his latest– Squidoo.com, a platform for publishing original, user-crafted lifestyle content on single topic pages–averages 13.1M U.S. visitors per month and 27M worldwide. In short, listen to his thoughts on “the circles of marketing,” taking risks, and, well, anything else.

The Coalition of Independent Authors: Speaking of those risks Mr. Godin talks about, if you’ve published (whether independently or not) you’ve taken the biggest one a creative type can.
